α-Particle Detector ARD-P
This alpha-particle detector uses internally prepared compound-semiconductor crystals and low-dead-layer electrodes for efficient direct detection. CdTe, perovskite and InSiTeᴈ versions are selected by measurement area, device thickness, vacuum environment and system structure. Thin-window/windowless entrances integrate with vacuum chambers, sample stages, digital spectroscopy and multichannel arrays. Optimized surface electrodes, passivation and low-noise readout produce clear pulse-height spectra for source characterization, surface-contamination measurement and particle experiments. Alpha particles deposit energy over a short path and create many electron–hole pairs. A bias field rapidly collects carriers into charge pulses proportional to deposited energy. Low-noise preamplification and digital multichannel analysis yield counts/energy spectra. Thin windows, low dead layers and a stable surface field are key to energy response.

40G High-Speed Indium Gallium Arsenide (InGaAs) Photodetector HSPD4040
Optical Detectors
Fiberwdm
Storage Temperature Range TSTG [Typical Values and Absolute Maximum Ratings]: typical:-45~+85; Rated: -55~+85 Operating Case-Temperature Range TC [Typical Values and Absolute Maximum Ratings]: typical:25; Rated: -40~+85 Bias Voltage VR [Typical Values and Absolute Maximum Ratings]: typical:5; Rated: 5~6
HSPD4040 is a high-speed detector module for digital/analog applications. An InGaAs PIN photodiode responds over1250–1650nm with matching electronics. Maximum bandwidth is40GHz, supply+5V, input standard single-mode9/125μm fiber, and RF output a2.92mm connector matched to50ohms. A sealed housing weighs under20g. The description states ROHS2.0 compliance with restrictions on hazardous substances in electrical/electronic equipment. After nearly two years of R&D,广州瑞东 developed two fully domestic high-speed PD products described as exceeding18GHz and40GHz bandwidth. The18GHz version has rise time<20ps and the40GHz PD<8.5ps. Responsivity is described as matching or exceeding comparable Finisar/Thorlabs imports,with well-controlled tail ringing. Without a TIA,the detectors provide very low noise for high-speed communications and femtosecond-laser testing at high cost effectiveness. The company's independently developed linear supply meets research needs for these detectors.
